The air duct formed between the protrusions can enable air circulation to realize air side heat exchange, thereby taking into account the heat exchange on the air side and the coolant side. There is no need to arrange additional fins, thereby enhancing the heat dissipation effect of the single tube, which is in line with the trend of increasingly compact layout space in the engine compartment.

[0047] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0048] Reference below Figures 1-9 The heat pipe 1 , the radiator 100 and the electrical device according to the embodiment of the present application are described.

[0049] Among them, such as Figure 1 As shown, the radiator 100 can be a flat tube type heat dissipation device; the electrical device can be a vehicle or an energy storage device, and the radiator 100 is used to dissipate heat for the heating components in the electrical device; the heat pipe 1 is a flat tube in the radiator 100 for the circulation of heat exchange fluid for heat exchange.

[0050] The heat dissipation pipe 1 of the embodiment of the present application includes: a base 11, and the base 11 can take into account heat exchange on both the air side and the heat exchange fluid side.

[0051] like Figure 4 As shown, the base 11 includes a main shell 111 and a protruding piece 112 protruding from the outside of the main shell 111 . The main shell 111 forms a flow channel 1111 , the protruding piece 112 forms an assembly groove 1121 , and an air duct 113 is formed between adjacent protruding pieces 112 .

[0052] The flow channel 1111 formed in the main shell 111 is used for allowing heat exchange fluid to circulate to achieve heat exchange. The heat exchange fluid can be a heat exchange fluid such as coolant or gas.

[0053] like Figure 3 and Figure 4 As shown, the assembly groove 1121 is used to install the spoiler 12 or the spacer. The spoiler 12 or the spacer can divide the flow channel 1111 into multiple sub-flow channels to increase the uniformity of the distribution of the heat exchange fluid in the flow channel 1111. The assembly groove 1121 can be connected to the flow channel 1111 so that when the spoiler 12 is not installed in the assembly groove 1121, the heat exchange fluid can flow into the protrusion 112 to form the assembly groove 1121. The side wall of the protrusion 112 can increase the heat dissipation area of the base 11 and improve the heat exchange effect on the heat exchange fluid side.

[0054] The main shell 111 and the protruding member 112 can be connected by welding or integral molding to reduce the risk of leakage of the heat exchange fluid.

[0055] The air ducts 113 formed between the protrusions 112 can allow air to circulate between the protrusions 112 , thereby achieving heat exchange of the heat dissipation pipe 1 on the air side and enhancing the heat dissipation effect of the heat dissipation pipe 1 .

[0056] like Figure 3 and Figure 4 As shown, the protrusion 112 may include one or more. In the case where there are multiple protrusions 112, the multiple protrusions 112 may be spaced apart and placed on the outside of the main shell 111, and an air duct 113 is formed between adjacent main shells 111. The air duct 113 allows air to pass through to achieve an air-side heat dissipation effect on the heat pipe 1, thereby eliminating the need to arrange additional fins; in the case where there is only one protrusion 112, both sides of the protrusion 112 may be in contact with the air to achieve an air-side heat dissipation effect.

[0057] In related technologies, with the rapid development of the automobile industry, people have higher and higher requirements for automobile safety, comfort, energy saving and environmental protection. With the popularization of EGR technology and twin-turbocharging technology, more and more components need to be cooled. As an important part of the automobile cooling system, the types and quantities of radiators are also increasing. The performance of the radiator directly affects the power, economy, life and emissions of the engine.

[0058] As engine power becomes higher and higher, the application of new technologies requires more and more parts to be arranged in the engine compartment. The heat load in the engine compartment is increasing, but the layout space is becoming increasingly compact. How to improve the heat exchange efficiency of the radiator without changing the layout conditions and reasonably controlling energy consumption is currently a hot topic in the radiator field.

[0059] Most passenger car radiators are flat tube radiators with limited heat exchange capacity. Improving heat dissipation performance is usually achieved by increasing the number of flat tubes, which is not conducive to improving the compactness and economy of the radiator and does not conform to the trend of increasingly compact layout space in the engine compartment.

[0060] In this regard, an embodiment of the present application provides a heat dissipation pipe 1, in which a protrusion 112 protruding from the outside of the main shell 111 is provided on the outside of the main shell 111, and a flow channel 1111 formed in the main shell 111 is used for circulation of heat exchange fluid to realize fluid-side heat exchange, and an air duct 113 formed between the protrusions 112 can allow air to circulate to realize air-side heat exchange, so that the heat dissipation pipe 1 itself can take into account both air-side and coolant-side heat exchange, without the need to arrange additional fins, thereby enhancing the heat dissipation effect of the heat dissipation pipe 1, which is in line with the trend of increasingly compact layout space in the engine compartment.

[0061] In some embodiments, as Figure 3 and Figure 4 As shown, the base 11 is an integrally formed structure, and the main shell 111 and the protruding member 112 can be formed by sheet metal stamping to reduce production difficulty.

[0062] In some embodiments, the substrate 11 is a thin shell structure, and the thickness of the substrate 11 is relatively small, which is beneficial to heat exchange between the inner and outer sides of the substrate 11 and improves heat exchange efficiency.

[0063] In some embodiments, as Figure 2 and Figure 3 As shown, the side wall of the protrusion 112 facing the adjacent protrusion 112 is provided with a spoiler structure 1122, and the spoiler structure 1122 protrudes from the side wall of the protrusion 112. The setting of the spoiler structure 1122 can increase the curvature of the air duct, increase the turbulence on the air side in the air duct, and thus enhance the heat exchange on the air side.

[0064] Exemplarily, the spoiler structure 1122 may be a spoiler groove, the notch of which faces the assembly groove 1121 to form an air cavity; or, the spoiler structure 1122 may be a solid structure to increase the heat dissipation area of the protrusion 112 and enhance the heat dissipation effect.

[0065] like Figure 2 and Figure 3 As shown, a plurality of spoiler structures 1122 may be arranged, and the plurality of spoiler structures 1122 are distributed in an array along the side wall of the protrusion 112 to further increase the heat dissipation area of the protrusion 112 and enhance the heat dissipation effect.

[0066] The spoiler structure 1122 and the side wall of the protrusion 112 are integrally formed to reduce the risk of leakage of the heat exchange fluid in the protrusion 112 .

[0067] For example, the side wall of the protrusion 112 is punched to form a spoiler structure 1122 , and the spoiler structure 1122 may be a spherical protrusion or a teardrop-shaped protrusion.

[0068] In some embodiments, as Figure 2 and Figure 3 As shown, the heat pipe 1 also includes: a spoiler 12, which is installed in the assembly groove 1121, and at least a portion of the spoiler 12 is located in the flow channel 1111 to divide the flow channel 1111 into multiple sub-flow channels, so as to increase the uniformity of the distribution of the heat exchange fluid in the flow channel 1111, thereby increasing the uniformity of the temperature.

[0069] The spoilers 12 include multiple spoilers 12 , which are assembled one-to-one with the multiple assembly grooves 1121 to divide the flow channel 1111 into multiple sub-flow channels. The number and specifications of the spoilers 12 can be adaptively set according to the specifications of the main shell 111 .

[0070] In the related technology, the traditional flat tubes are of a single form, and most of the flat tubes are traditional straight flat tubes with 3 to 4 channels. The fluid side turbulence is limited, the flow resistance is large, and the heat exchange capacity is limited, which is not conducive to improving the compactness and economy of the radiator; at the same time, the flat tubes are easy to scale, difficult to clean, and easy to cause blockage, which is not conducive to the safety of long-term use.

[0071] In this embodiment, the flow channel 1111 can be divided into multiple sub-flow channels by providing a spoiler 12. The spoiler 12 can increase the contact area between the heat exchange fluid and the tube wall, thereby improving the efficiency of heat exchange. At the same time, the spoiler 12 can control the flow direction and speed of the fluid in the flow channel 1111, improve the scaling condition, and achieve a turbulent effect, so as to optimize the heat transfer process and enhance the heat exchange capacity.

[0072] The spoiler 12 can be detachably connected to the base 11 by plugging into the assembly groove 1121 , and the two do not need to be welded, which reduces the difficulty of assembly. At the same time, the spoiler 12 can be recycled, which can effectively reduce costs.

[0073] In some embodiments, as Figure 4 As shown, the assembly groove 1121 is connected to the flow channel 1111. When the spoiler 12 is not installed in the assembly groove 1121, the heat exchange fluid can flow into the assembly groove 1121 formed by the protrusion 112. The side wall of the assembly groove 1121 can increase the heat dissipation area of the base 11 and improve the heat exchange effect on the heat exchange fluid side.

[0074] like Figure 4 As shown, opposite sides of the main shell 111 are provided with oppositely arranged protrusions 112, and the opposite sides of the main shell 111 can both achieve air-side heat dissipation, thereby improving the collective heat dissipation effect.

[0075] A plurality of protrusions 112 are disposed on opposite sides of the main housing 111 to facilitate installation of a plurality of spoilers 12 .

[0076] like Figure 3 As shown, the spoiler 12 is installed in the relatively arranged assembly grooves 1121, that is, the two ends of the spoiler 12 are installed in the relatively arranged assembly grooves 1121, and the spoiler 12 is plugged into the assembly grooves 1121, which reduces the difficulty of assembly and increases the reliability of assembly. At the same time, a small amount of heat exchange fluid can enter the gap between the spoiler 12 and the assembly groove 1121, which helps to generate turbulence during the flow of the heat exchange fluid, thereby enhancing heat exchange.

[0077] In some embodiments, the spoiler 12 includes a body 121 and a spoiler window 122 .

[0078] like Figure 8 and Figure 9 As shown, the body 121 is provided with through holes 1211, which allow the heat exchange fluid on both sides of the body 121 to flow, generate a turbulent flow effect, change the flow direction and flow rate of the heat exchange fluid, and improve the heat exchange effect of the heat exchange tube.

[0079] like Figure 8 and Figure 9As shown, part of the spoiler window 122 is connected to the body 121, and the rest of the spoiler window 122 is separated from the body 121. The spoiler window 122 can control the flow direction and flow speed of the fluid according to its own shape as needed.

[0080] The spoiler window 122 and the main body 121 can be integrally formed, or connected by welding, threaded connection, plug-in connection or other connection methods.

[0081] like Figure 6-Figure 9 As shown, the spoiler window 122 has a first state and a second state, and the spoiler window 122 can change its state according to the temperature of the heat exchange fluid in the flow channel 1111 or the action of the outer wall force.

[0082] like Figure 6 As shown, in the first state, the spoiler window 122 and the main body 121 are located in the same plane to block the through hole 1211. The blocking of the through hole 1211 can limit the passage of fluid. At the same time, the spoiler window 122 and the main body 121 are located in the same plane to reduce the spoiler effect generated by the spoiler window 122 and reduce the heat dissipation capacity of the heat pipe 1. This state can reduce energy consumption for working conditions with low engine heat dissipation requirements.

[0083] like Figure 7 、 Figure 8 and Figure 9 As shown, in the second state, the spoiler window 122 is deformed relative to the main body 121 to open the through hole 1211, thereby allowing the fluid to pass through the through hole 1211. Since the spoiler window 122 is bent relative to the main body 121 to form a warped surface, the contact area between the fluid and the spoiler window 122 can be increased. After the spoiler window 122 is warped, the spoiler effect is stronger, which can improve the heat dissipation efficiency of the heat pipe 1 and meet high heat dissipation requirements. This state can be used for working conditions where the engine has high heat dissipation requirements.

[0084] The deformation angle and height of the spoiler window 122 relative to the main body 121 can be adaptively set according to the temperature of the heat exchange fluid.

[0085] In some embodiments, as Figure 7 and Figure 8 As shown, the spoiler window 122 is provided with a through hole 1221. The through hole 1221 can reduce weight on the one hand, and can be used for the passage of heat exchange fluid on the other hand, thereby increasing turbulence and heat exchange uniformity and improving heat exchange effect.

[0086] The number and size of the through holes 1221 can be adaptively set according to the heat dissipation requirements and the size of the spoiler window 122 .

[0087] When the spoiler window 122 is deformed at a large angle, the through hole 1221 can effectively reduce the flow resistance and prevent the formation of backflow vortexes in the heat exchange fluid.

[0088] In some embodiments, as Figure 8 and Figure 9 As shown, the spoiler window 122 includes a first baffle 1222 and a second baffle 1223, which are alternately distributed along the extension direction of the body 121; in the second state, the first baffle 1222 and the second baffle 1223 are deformed toward opposite sides of the body 121 respectively.

[0089] In this embodiment, the first baffle 1222 and the second baffle 1223 are alternately distributed along the extension direction of the main body 121. When the first baffle 1222 and the second baffle 1223 are both in the second state, the first baffle 1222 and the second baffle 1223 can be deformed toward the opposite sides of the main body 121 respectively, thereby generating a turbulent effect on the heat exchange fluid on both sides of the main body 121 and improving the heat exchange effect.

[0090] In some embodiments, the spoiler 12 can be made of a shape memory material. For example, the spoiler 12 can be made of ordinary two-way shape memory material, multi-level two-way memory metal or two-way memory metal to achieve the deformation ability of the spoiler window 122 under different working conditions.

[0091] In some embodiments, the spoiler window 122 is a shape memory material. For example, the spoiler window 122 can be made of ordinary two-way shape memory material, multi-level two-way memory metal or two-way memory metal and other materials to achieve the deformation ability of the spoiler window 122 under different working conditions while reducing costs.

[0092] In some embodiments, when the temperature of the heat exchange fluid in the flow channel 1111 reaches a target temperature value, the spoiler window 122 switches from the first state to the second state.

[0093] In this embodiment, the spoiler window 122 can switch to different states according to the temperature of the heat exchange fluid in the flow channel 1111, which can effectively match the heat exchange requirements of the engine under different working conditions and improve the economy and comfort of the passenger car.

[0094] Under low engine load and low heat dissipation conditions, the spoiler window 122 occurs as follows Figure 7 The small warping shown or Figure 6 As shown, the low heat dissipation requirement of the engine can be met without deformation; Figure 8 and Figure 9 As shown, under high-load conditions of the engine, the spoiler window 122 will bend and deform at a large angle, and the spoiler effect will be stronger, thereby achieving rapid heat dissipation.

[0095] In some embodiments, as Figure 6 As shown, when the heat exchange fluid in the flow channel 1111 is in the first temperature range, the spoiler window 122 remains in the first state; Figure 7 、 Figure 8 and Figure 9 As shown, when the heat exchange fluid in the flow channel 1111 is in the second temperature range, the spoiler window 122 is maintained in the second state.

[0096] The target temperature value is a critical value between the first temperature range and the second temperature range, and the target temperature value can be adaptively set according to heat dissipation requirements.

[0097] For example, when the heat exchange fluid in the flow channel 1111 is in the second temperature range, the deformation angle of the spoiler window 122 can be continuously changed according to the temperature of the heat exchange fluid in the flow channel 1111; or, the deformation angle of the spoiler window 122 can be changed in multiple levels according to the temperature of the heat exchange fluid in the flow channel 1111; or, the deformation angle of the spoiler window 122 remains unchanged.

[0098] According to the material type of the spoiler window 122, at least three working states of the spoiler window 122 can be formed:

[0099] First, when the heat exchange fluid in the flow channel 1111 is in the second temperature range, the deformation angle of the spoiler window 122 remains unchanged.

[0100] In this embodiment, the heat exchange fluid in the flow channel 1111 is in the first temperature range, the engine heat dissipation requirement is relatively low, and under low load conditions, the spoiler window 122 of the spoiler 12 in the base 11 is located at Figure 6 In the first state shown, the spoiler window 122 does not warp, and the heat exchange fluid can flow between adjacent sub-channels through the through holes 1221 on the spoiler window 122. The through holes 1221 act as jets, which can increase the turbulence and heat exchange uniformity, enhance the heat exchange to meet the heat exchange requirements of the engine, and the number and arrangement of the through holes 1221 can be adjusted according to the actual heat exchange requirements. As the heat dissipation demand of the engine increases, under high load conditions, the heat exchange fluid in the flow channel 1111 is in the second temperature range, such as Figure 7 、 Figure 8 and Figure 9 As shown, the spoiler window 122 of the spoiler 12 in the base 11 is in the second state, and the spoiler window 122 of the spoiler 12 quickly warps. After the warping, the spoiler window 122 has a stronger spoiling effect, reduces the flow resistance, achieves rapid heat dissipation, and meets the high heat dissipation requirements.

[0101] In this embodiment, the spoiler window 122 or the entire spoiler 12 can be made of a common two-way shape memory material. For example, the common two-way shape memory material can be cross-linked polycaprolactone, cross-linked ethylene-vinyl acetate copolymer, cross-linked polyethylene or polyester polyurethane.

[0102] Secondly, when the heat exchange fluid in the flow channel 1111 is in the second temperature range, the deformation angle of the spoiler window 122 can be continuously changed according to the temperature of the heat exchange fluid in the flow channel 1111 .

[0103] In this embodiment, in the second state, the deformation angle of the spoiler window 122 is positively correlated with the temperature of the heat exchange fluid in the flow channel 1111 .

[0104] The deformation angle of the spoiler window 122 of the spoiler 12 in the base 11 can be continuously changed according to the change of the temperature of the heat exchange fluid in the flow channel 1111 .

[0105] In this embodiment, as the heat dissipation requirement of the engine changes, the deformation angle of the spoiler window 122 of the spoiler 12 in the base 11 changes as the temperature of the heat exchange fluid changes. Figure 7-Figure 9 As shown in the continuous changes, the heat dissipation of the engine is different, the temperature of the heat exchange fluid is different, the spoiler window 122 of the spoiler 12 in the base 11 undergoes warping deformation at different angles, the temperature of the heat exchange fluid increases, the deformation angle of the spoiler window 122 increases, the flow resistance decreases, the temperature of the heat exchange fluid decreases, and the deformation angle of the spoiler window 122 of the spoiler 12 in the base 11 decreases. The heat dissipation of the radiator 100 always matches the heat dissipation requirements of the engine, thereby meeting the different heat dissipation requirements of the engine and reducing energy consumption.

[0106] In this embodiment, the spoiler window 122 or the entire spoiler 12 may be a two-way memory metal member. For example, the two-way memory metal may be a styrene resin-based shape memory polymer composite material or an epoxy resin-based shape memory polymer composite material.

[0107] Thirdly, the deformation angle of the spoiler window 122 of the spoiler 12 in the base 11 can be changed in multiple levels according to the temperature of the heat exchange fluid in the flow channel 1111.

[0108] Among them, the second temperature range has multiple temperature sub-ranges, and the deformation angle of the spoiler window 122 of the spoiler 12 in the base 11 has multiple gears. When the heat exchange fluid in the flow channel 1111 is in one of the multiple temperature sub-ranges, the spoiler window 122 remains in the corresponding gear.

[0109] The multiple temperature sub-intervals correspond one-to-one to the multiple levels of deformation angle of the spoiler window 122 .

[0110] In this embodiment, if Figure 6 As shown, when the engine has no heat dissipation demand, the heat exchange fluid in the flow channel 1111 is in the first temperature range, the spoiler window 122 of the spoiler 12 in the base 11 is in the first state, and the spoiler window 122 does not warp.

[0111] In the second temperature range, the spoiler window 122 of the spoiler 12 in the base 11 is in the second state. Figure 7 As shown, when the engine heat dissipation demand is low and it is in a low-load operating condition, and the heat exchange fluid in the flow channel 1111 is in the first temperature sub-range, the spoiler window 122 undergoes a primary warping with a small deformation angle. The slight warping of the spoiler window 122 and the through hole 1221 increase the spoiler flow and enhance the heat exchange. Figure 8 As shown in FIG. 1 , as the heat dissipation demand of the engine increases, under medium load conditions, the temperature of the heat exchange fluid in the flow channel 1111 rises to the second sub-interval, and the spoiler window 122 of the spoiler 12 in the base 11 undergoes secondary warping. After the warping, the spoiler window 122 has an enhanced spoiling effect and an increased heat dissipation speed. Figure 9 As shown, as the engine heat dissipation demand continues to increase, under high-load conditions, the temperature of the heat exchange fluid in the flow channel 1111 rises to the third sub-interval, and the spoiler window 122 of the spoiler 12 in the base 11 undergoes three-level warping, with the largest deformation angle, the strongest degree of spoiling, and the best heat exchange capacity.

[0112] In this embodiment, the spoiler window 122 or the entire spoiler 12 may be a multi-stage bidirectional memory metal part. For example, the multi-stage bidirectional memory metal may be a cross-linked polymer synthesized from multiple crystals (T-T3PPD-P4PCL), etc.

[0113] According to the heat pipe 1 provided in the present application, by arranging a spoiler 12 in the base 11, on the one hand, the spoiler window 122 on the spoiler 12 can be deformed according to the temperature of the heat exchange fluid in the flow channel 1111. When the spoiler window 122 is deformed, the through hole 1211 on the main body 121 is opened, which can realize the heat exchange of the heat exchange fluid in the sub-flow channel and improve the temperature uniformity in the heat pipe 1; secondly, after the spoiler window 122 on the spoiler 12 is deformed, the spoiler can enhance the turbulence and continuously change the flow direction and flow velocity of the heat exchange fluid, increase the heat exchange efficiency, reduce the scaling in the base 11, reduce the risk of blockage of the heat pipe 1, and extend the heat exchange capacity, safety and life of the heat pipe 1; thirdly, by arranging a through hole 1221 on the spoiler window 122, the overall weight of the heat pipe 1 can be reduced, and the heat exchange fluid can pass through, thereby increasing the turbulence and heat exchange uniformity, and further increasing the heat exchange effect.

[0114] like Figure 1 As shown, an embodiment of the present application further provides a radiator 100 , comprising the heat pipe 1 of any one of the above embodiments.

[0115] According to the radiator 100 provided in the present application, by setting any of the above-mentioned heat pipes 1, a spoiler 12 is set in the base 11 of the heat pipe 1. On the one hand, the spoiler window 122 on the spoiler 12 can be deformed according to the temperature of the heat exchange fluid in the flow channel 1111. When the spoiler window 122 is deformed, the through hole 1211 on the main body 121 is opened, which can realize the heat exchange of the heat exchange fluid in the sub-flow channel and improve the temperature uniformity in the heat pipe 1; secondly, after the spoiler window 122 on the spoiler 12 is deformed, the turbulence can be enhanced to continuously change the flow direction and flow velocity of the heat exchange fluid, increase the heat exchange efficiency, reduce the scaling in the base 11, reduce the risk of blockage of the heat pipe 1, and extend the heat exchange capacity, safety and life of the heat pipe 1; thirdly, by setting a through hole 1221 on the spoiler window 122, the overall weight of the heat pipe 1 can be reduced, and the heat exchange fluid can pass through, thereby increasing the turbulence and heat exchange uniformity, and further increasing the heat exchange effect.

[0116] The number and arrangement of the heat dissipation pipes 1 can be adaptively improved according to heat exchange requirements.

[0117] In some embodiments, as Figure 2 As shown, the heat dissipation tube 1 may include multiple heat dissipation tubes 1, and the multiple heat dissipation tubes 1 are stacked to improve the heat dissipation efficiency. No fins are required between adjacent heat dissipation tubes 1, which can reduce production costs and production difficulty. At the same time, the distance between two adjacent heat dissipation tubes 1 can be shortened, which not only improves the heat exchange efficiency of the radiator 100, but also improves the compactness of the radiator 100, which is in line with the trend of increasingly compact layout space in the engine compartment.

[0118] In some embodiments, as Figure 1 As shown, the radiator 100 includes a fixing bracket and an end connection piece.

[0119] Multiple heat pipes 1 are installed on a fixed bracket, and multiple heat pipes 1 are assembled to form the heat dissipation core of the radiator 100. The fixed bracket includes an upper fixed plate 21 and a lower fixed plate 22. The upper fixed plate 21 and the lower fixed plate 22 are respectively arranged on the upper and lower sides of the heat dissipation core to increase the stability of the connection of the multiple heat pipes 1.

[0120] The end connectors are provided on both sides of the heat dissipation tube 1 , and are used to connect two adjacent heat dissipation tubes 1 so that the cooling fluid can flow between the multiple heat dissipation tubes 1 .

[0121] In some embodiments, as Figure 1As shown, the radiator 100 also includes: an inlet auxiliary water tank 31 and an outlet auxiliary water tank 32. The inlet auxiliary water tank 31 is connected to the water inlet side of the heat dissipation pipe 1 to provide heat exchange fluid for the heat dissipation pipe 1, and the outlet auxiliary water tank 32 is connected to the water outlet side of the heat dissipation pipe 1 to collect the heat exchange fluid. The inlet auxiliary water tank 31 is provided with a heat exchange fluid inlet 33, and the outlet auxiliary water tank 32 is provided with a heat exchange fluid outlet 34.

[0122] The water inlet auxiliary water tank 31 and the water outlet auxiliary water tank 32 are installed on a fixed bracket.

[0123] like Figure 1 As shown, the flow path of the heat exchange fluid of the radiator 100 is as follows:

[0124] The water inlet auxiliary water tank 31 is connected to a coolant inlet pipeline. The coolant flows in from the heat exchange fluid inlet 33 and flows downward through the water inlet auxiliary water tank 31. During the downward flow, the coolant is evenly distributed to the flow channel 1111 of the main shell 111 through the spoiler 12. The coolant in the flow channel 1111 of the main shell 111 is disturbed by the spoiler 12 and then gathers into the water outlet auxiliary water tank 32 after taking away the heat. Then it flows downward to the heat exchange fluid outlet 34 and flows out. The upper fixing plate 21 and the lower fixing plate 22 serve to fix the water inlet auxiliary water tank 31, the water outlet auxiliary water tank 32 and the heat dissipation pipe 1.

[0125] An embodiment of the present application further provides an electrical device, comprising the heat sink 100 of any one of the above embodiments.

[0126] The electrical device may be a vehicle, a water heater or other energy storage device.

[0127] According to the electrical device of the present application, by setting any of the above-mentioned radiators 100, the radiator 100 includes a heat pipe 1, and a spoiler 12 is set in the base 11 of the heat pipe 1. On the one hand, the spoiler window 122 on the spoiler 12 can be deformed according to the temperature of the heat exchange fluid in the flow channel 1111. When the spoiler window 122 is deformed, the through hole 1211 on the main body 121 is opened, which can realize the heat exchange of the heat exchange fluid in the sub-flow channel and improve the temperature uniformity in the heat pipe 1; secondly, after the spoiler window 122 on the spoiler 12 is deformed, the turbulence can be enhanced to continuously change the flow direction and flow velocity of the heat exchange fluid, thereby increasing the heat exchange efficiency, reducing the scaling in the base 11, reducing the risk of blockage of the heat pipe 1, and extending the heat exchange capacity, safety and life of the heat pipe 1; thirdly, by setting a through hole 1221 on the spoiler window 122, the overall weight of the heat pipe 1 can be reduced, and the heat exchange fluid can pass through, thereby increasing the turbulence and heat exchange uniformity, and further increasing the heat exchange effect.
